Tyre Size calculator. (not online/web based tool,)

Its a standalone flash based tool. You need Adobe/macromedia flash player 9.


Download and use!

Now this calculator has made me scratch my head regarding the speedo error thing

My car Does 100Km/hr at 2750 RPM on stock tyres.

If I upgrade to 196/60/14 the Difference would be 2.5%.
70MPH would be 71.5 MPH.

that means speedo will show less reading for a particular RPM than stock tyres.

Shouldnt it be more since the overall diameter is increasing and the car would be revving less?

Asking this since my bike used to do 100@6.5K RPM on stock tyres
after upsizing one size it did 100@6.2K RPM

RPM has no connection to your speedo reading. The speedo takes its reading by calculating the number of revolutions in the tyre - so if the tyre becomes larger or smaller the speedo reading will change accordingly.
The RPM reading that you see in the dashboard instrument panel is related to the engine's working speed. Not really connected to the speedo in any way.

Can someone please solve my confusion??
The stock tyre size of a Fiat Punto Active variant is 165/80-R14, Emotion is 175/70-R14 and Emotion Pack is 195/60-R15 (pre-2012 models).
Now, according to the tyre size calculator, it is not recommended to up-size the Active variant to the tyre size of an Emotion/E Pack variant, or up-size an Emotion variant to Emotion Pack's tyre size.
I for one, don't believe that Fiat would calibrate the meters differently for different variants; it just doesn't make sense.
What's the funda here? Is it a plain goof up on the part of Fiat India or is there some basic reasoning that eludes me?

Default Re: Tire size and Speedo error calculator

I am looking to upgrade the stock tyres (155/65 R14) of my WagonR. Though I have the option of 165/65 R14 I am more interested in 175/65 R14. The error due to the upsize is going to be 4.7% in the latter versus 2.3% in the former. Should I go ahead with this upgrade?
There is another alternative of 175/60 R14(1.5%) but I don't see any tyre brands offering them (available in GY GT3 and Yoko A-Drives only).
